Embarrassed to admit this but something that should be simple is defeating me.
Bought a new Kisan decaying tail light to help keep vehicles behind me alert.
The book says you stick a small screw driver in a hole right above the license plate holder push up forward this tab and then pop the tail light housing out. Well tried big screwdrivers, short ones etc. Finding a metal tab and can feel that I'm pushing this thing up and forward but the tail light housing is not budging. I can twist it a little and tell that the tab is there but can't get it to let go.

From looking under the fender looks like I could take the dogs ass off and maybe that would make it easy to change. Was not that desperate, my tail light works just want to get a little more attention. I change my own oil have installed quite a few parts myself but at the moment that tail light housing is not coming off.

You would probably be better off removing the passenger pillion and then removing the rear fender to access the tail light it might take you 5 minutes to remove the both of them....The metal tab on the tail lightis pretty frail and sometimes tends to break if your not careful.

Thanks to all. Tomorrow when I have the hardware to mount my baseplate, luggage rack, Hepco & Becker storage box, I will put the new light in while I have it all apart. Once again I have discovered the Harley Owners Manual and even the Maintenance Manual don't have the easiest way to accomplish something documented..

Took the fender off. Takes ten extra minutes. Louis is right your can see the metal tab but most importantly the tiny thin plastic tabs at the top that would break in a heartbeat if you pulled on the top without having the metal tab pressed tightly in. Installed the base plate and luggage rack. Ran out of time will put the storage box on sometime this week and then post a picture. Just for reference my base plate is used did not want to pay what Harley is asking for new ones. I could see some corrision in the luggage rack mounting holes. Used some anti-sieze when I put the bolts in. Bad design should be some plastic caps or something to moisture from getting in the threads. Maybe a dab of clear RTV on top of each screw as protection. Wrong Kisan bulb. I need a bayonet mount and the one I bought is a wedge. Thanks for the good advice.
